Problems solved by technology
[0003] At present, the protection of underwater pipes and cables adopts the steel structure scheme. The steel structure has problems such as heavy weight, serious corrosion problems, and various operations.
The installation resource requirements, design schemes, installation schemes, and corrosion protection schemes required by steel protection structures all bring certain challenges to engineering development. It is easy to increase the weight due to steel protection, which will lead to adjustment of the overall design scheme and installation In case of substantial increase in ship days and engineering costs

Embodiment Construction
[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] like figure 1 As shown, the composite material protection cover for an underwater umbilical according to an embodiment of the present invention includes at least one protection unit 1 for covering and protecting the underwater umbilical.
[0022] The protection unit 1 includes a protective cover main body 10 , a first connecting cover 20 connected to one end of the protective cover main body 10 , and a second connecting cover 30 connected to the opposite end of the protective cover main body 10 . The protective cover main body 10 is used to cover the underwater umbilical and extend along the axial direction of the underwater umbilical, and the length can be set as required. The cross section of the protective co...

The invention discloses a composite material protection cover of an underwater pipe cable. The composite material protection cover comprises at least one protection unit made of a composite material,wherein the protection unit comprises a protection cover main body used for covering an underwater pipe cable and extending in the axial direction of the underwater pipe cable, a first connection cover connected to one end of the protection cover main body and arched in an arc shape, and a second connection cover connected to the other opposite end of the protection cover main body and arched in an arc shape, and the first connecting cover is movably matched with the second connecting cover of the other protection unit, so that the two protection units are movably connected. According to the composite material protection cover of the underwater pipe cable, the protection unit covers the underwater pipe cable to protect the underwater pipe cable, so that the underwater pipe cable is effectively prevented from being damaged by falling objects, fishing nets and fishing gears; the protection cover has the advantages of light weight, high strength, tight protection, smooth surface, corrosion resistance, impact resistance and the like, and is convenient to hoist and transport; and the manufacturing mold can be repeatedly used, the manufacturing period is short, and the construction period and construction cost are reduced.
Description
technical field [0001] The invention relates to an underwater umbilical cable protection device, in particular to a composite material protective cover for an underwater umbilical cable. Background technique [0002] With the rapid development of my country's offshore oil and gas and offshore wind power, a large number of underwater pipes and cables will be laid. How to protect them, resist mechanical damage from third-party activities such as fishing activities and anchoring, and protect natural conditions such as sand waves and sand ridges The challenges brought about have become a problem that cannot be ignored. [0003] At present, the protection of underwater pipes and cables adopts steel structure schemes. Steel structures have problems such as heavy weight, serious corrosion problems, and various operations. The installation resource requirements, design schemes, installation schemes, and corrosion protection schemes required by steel protection structures all bring c...
